Specification of Letters Patent.

Application filed November 2, 1910.

Patented Apr. 23, 1912.

Serial No. 590,304.

To all whom it may concern:

Be it known that I, DULANEY IV. FAULK, a. citizen of the United States,residing at Coatesville, in the county of Chester and State ofPennsylvania, have invented certain new and useful Improvements inPrintingFrames; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in printing framesand more particularly to that class adapted to be used in printingphotographs, post cards, etc., and my object is to provide a framehaving an opening therein over which the plates or films to be printedare placed.

A further object is to provide yielding means for holding the plate orfilm in engagement with the frame.

A further object is to so construct the holding device as to form aguide for the sensitized card on which the imprint is to be made.

A further object is to provide means for moving the holding device outof engagement with the plate or film.

A further object is to provide a clamp for holding the sensitized paperonto the plate or film while being printed.

A further object is to provide yielding hinges for holding the clamp.

A further object is to provide a latch for holding the clamp in itsclosed position, and, a further object is to provide means for swingingthe clamp to an open position when released from the latch.

Other objects and advantages will be hereinafter set forth and pointedout in the specification.

In the accompanying drawings, which are made a part of this application,Figure 1 is a perspective view of the printing frame, showing the partsclamped in position for printing purposes. Fig. 2 is a perspective viewwith the clamp in its elevated position. Fig. 3 is a perspective viewlooking at the opposite edge from that shown in Fig. 2. Fig. f is asectional view as seen on line M, Fig. 1, and, Fig. 5 is a sectionalView as seen on line 55, Fig. 1.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the frame,which may be con structed in any preferred manner and 9. is a handleportion therefor, while 3 indicates an opening through the bodyof theframe over which the plate or film & rests during the printingoperation.

The plate after being placed over the opening 3 is securely held inposition by an L-shaped bar 5, which bar is held in engage ment with oneedge and one end of the plate under pressure by means of bowed springs6, one end of each of the springs being secured to the frame while theopposite ends thereof are attached to the bar. In order to elevate thebar out of engagement with the plate a shaft 7 is positioned parallelwith and above the longitudinal portion of the bar engaging the edge ofthe plate and is mounted in suitable standards 8 extending upwardly fromthe frame. The pintles 9 of the shaft 7 are eccentrically arranged atthe ends of the shaft 7 so that when the shaft is rotated it will. actas a cam and by extending collars 10 around the shaft and attaching thesame by pivots parallel with the shaft 7, to cars 11 on the bar 5, saidbar will be elevated when the shaft is rotated. To facilitate therotation of the shaft 7 a milled knob or the like 12 is attached to oneof the pintles and by grasping said knob the shaft can be easily rotatedin either direction. After the plate has been placed in position overthe opening and the bar 5 lowered into engagement therewith, thesensitized card can be quickly and accurately placed in position overthe plate, as the inner edges of the bar will form a perfect guide forthe card. After a film, has been placed in position over the opening 3and the card is placed in position over the film a clamp 13 is loweredinto position over the card, the engaging face of said clamp beingpreferably provided with felt 1a, or other cushioning material. One endof the clamp is secured to a block 15 at one end of the frame throughthe medium of hinges 16, said hinges being preferably composed of threeleaves 17, 18 and 19, the leaf 17 being attached to the clamp and theleaf 19 to the outer side of the block, while the leaf 18 is hinged atits opposite edges to and between the other two leaves and extends overthe upper face of the block. The object in constructing the hinges inthis manner is to accommodate plates or films of varying thicknesses andwhen a plate, negative, or film of greater thickness is used, the threepart hinge will permit the clamp to rise sufliciently to accommodate theplate and at the same time maintain a uniform pressure on the plate.

The section 18 of the hinge is normally held seated on the upper face ofthe block by extending a screw 20 through an opening in the section 18and into the block 15, a tension spring 21 being introduced around thescrew and between the head thereon and the upper face of the section 18of the hinge. A suitable cushion may be inserted under the section 18and this with the spring 21 will give a yielding pressure on the hingeto accommodate various thicknesses of plates or films as before stated.The three-part hinge permits the clamp to be kept in a horizontalposition while being raised or lowered. The clamp 13 is held in itslowered position through the medium of a latch 22, which is pivotallymounted between ears on the frame 1, said latch being so situated tha'the inner end thereof will extend over and engage a tongue 2% carried bythe clamp and the latch is held in engagement with the tongue by placinga spring 25 between the face of the frame 1 and the handle portion ofthe latch. In order to immediately swing the clamp upwardly and fromover the card 26, a flat spring 2? is provided, one end of the springbeing secured to the outer face of the block 15 while the opposite endthereof is intro duced below a clip 28 on the outer face of the clampand it will be readily seen that when the clamp is thrown to its loweredposition the elasticity of the spring will be exerted in such manner asto immediately elevate the clamp when the latch is released therefrom.

By this form of device it will be seen that the printing operation maybe greatly facilitated, as the plates and cards can be quickly placedthereon or removed therefrom, and, it will likewise be seen that thedevice can be produced at a minimum expense and rendered extremelystrong and durable.

What I claim is:

l. in aprinting device the combination with a frame having an openingtherethrough, of an L-shaped bar adjacent said opening, means to holdsaid bar in engagement with the frame under pressure, collars pivoted tothe bar, an eccentrically mounted shaft extending through said collarsadapted to raise the bar when the shaft is rotated, a clamp hinged tosaid frame, means to hold said clamp in its lowered position undertension and a spring adapted to swing the clamp upwardly when theholding means is released.

2. A printing frame comprising a base having an exposing opening, ablock transversely secured to the base in position parallel with and ata short distance from one end of said opening, a clamp of substantiallythe thickness of the block adapted to cover the opening, having one endadjacent to the inner side of said block, a three-part hinge having oneleaf secured to the clamp, a second leaf connected to the first by apintle lying over the space between the clamp and block said second leafbeing adapted to lie upon the top of the block, and the third leaf oinedto the second by a pintle at the outer edge of the block and secured tothe outer side of the block, the second leaf having an opening throughit, a screw extended through said opening into the block, and a springcoiled around the body of the screw between its head and the leaf.

3. A printing frame comprising a base having an exposing opening,rightangular shaped springs secured to one longitudinal side of the baseextending upward and having their upper portions to substantialparallelism with the top of the base and slightly projecting over theexposing opening, an L shaped bar above the base having its longitudinalportion projecting over and parallel with one side of the opening andsecured under and to the overhanging ends of the springs, bearingsmounted on the base, a shaft above and parallel with the longitudinalportion of the L shaped bar and eccentrically ournaled in said bearings,collars around the shaft having downward extensions, and ears on the Lshaped bar, and pintles parallel with the shaft pivotally connecting theextensions with the ears.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
